Best PSU for RTX 3070 Ti

The two best PSUs to ensure your GPU is always running smoothly

Table of Contents

When you’re building a PC or upgrading your rig, there’s one component that’s very easy to miss, yet it’s essential for the best performance.  A power supply unit (PSU) is the component that gives power to every single component inside of your PC. If you have a PSU that doesn’t give enough power, you can expect severely degraded performance – not to mention lots of errors.

The Nvidia GeForce RTX 3070 Ti is still a pretty powerful graphics card. Nvidia recommends at least 650W for this GPU, but it’s always a good idea to have more power just in case you want to upgrade in the future.

With that in mind, let’s take a look at the best PSUs for the RTX 3070 Ti graphics card.

Best PSU for RTX 3070 Ti

Nvidia recommends at least a 650W PSU for the RTX 3070 Ti. However, it’s not a lot of power, if you want to upgrade your PC in the future it won’t be enough. We are going to look for PSUs that are at least 750-850W or above so that you don’t have to worry about your PSU while building your configuration.

The first PSU on our list is the Pystar 1000W Power Supply 80+ Gold. It sits currently at the top of the page on Amazon and for a very good reason. It’s very cheap at around $140, as the name suggests it’s highly efficient due to the 80+ Gold Rating, and it’s fully modular, meaning you can disconnect any cables you don’t need. It comes with a quiet 140 mm fan, and it also comes with a 10-year warranty so you can make sure your investment is well-protected for the future.

Another PSU that you might want to check out is the ASUS ROG Thor 850 Certified 850W. It has a bit less power than our previous PSU, but it should be enough for the RTX 3070 Ti. But it’s recommended to get a PSU that packs more power than what your PC currently needs, especially if you want to overclock your GPU or do any high-performance task such as gaming. It comes with an 80 Plus Gold certification, it’s energy-efficient, and the ROG heatsinks cover every critical component. Due to its dual ball fan bearings, it can last twice as long as a sleeve bearing design. Built-in 0 dB technology makes sure you can enjoy some silence when the PC experiences a low to medium workload.

Best Budget PSU for RTX 3070 Ti

This next budget PSU is a favorite amongst PC builders, it’s very cheap, yet it’s high-end and it has enough power for your RTX 3070 Ti. It is the Corsair RMX Series (2021), RM750x. If you just want a PSU that can run your RTX 3070 Ti, this one should do the job. However, it’s recommended to get a bigger PSU especially if you are planning to upgrade in the future. This PSU is fully-modular and spares you the headache of managing cables. It comes with a 135 mm magnetic levitation bearing fan, which makes it very quiet.


There are loads of PSUs on the market to choose from. It’s recommended to choose a reputable brand so that in case your PSU fails, you are protected by a warranty. Before deciding to buy a PSU, always make sure you get a unit that can account for every component’s power need.
